摘要
We report a ring cavity passively harmonic mode-locked thulium-doped fiber laser(TDFL)using a newly developed single-wall carbon nanotube-based saturable absorber.The TDFL generates the 25thharmonic mode-locked stretched pulse train with a high repetition rate of 213 MHz and a pulse duration of 710 fs.The laser operates at 1901.6nm with an average power of 1.8.9 mW,which corresponds to the pulse energy of O.OOSnJ,at 1552nm pump power of 719 mW.The peak-to-background ratio is measured to be 60 dB,which indicates the stability of the laser.
